Commit ff29322b ("test: canonicalize test runner path") from 2014
changed the test runner to call `realpath(3)` on `argv[0]` in order
to fix the `get_currentexe` test failing with the autotools build when
the executable path contained symbolic links but that is now causing
the `spawn_reads_child_path` test to fail on z/os with the cmake build.
Fix that by only doing path canonicalization in the `get_currentexe`
test, not always.
An auxiliary fix is applied to the `process_title_threadsafe` test
because it assumed that setting the process title to a long string,
then reading it back produces in the original string.
On some platforms however the maximum size of the process title is
limited to the size of the `argv` vector.
Because the test runner used absolute paths until now, the argv vector
was bigger than it is with relative paths, big enough to let this bad
assumption go unnoticed until now.
Minor fixes are applied to tests that assumed 1024 for the maximum
path size because this commit makes visible that some of the CI matrix
systems support much longer paths.

The test checks that the creation time equals the birth time on systems
that support the notion of birth time (macOS, Linux.)
The test was flaky because there was a write taking place between the
creation of the file and the fstat() call, sometimes changing the ctime
by fractions of milliseconds... First fstat(), only then write().

On Windows, `fs__open()` maps `UV_FS_O_DIRECT` to
`FILE_FLAG_NO_BUFFERING`.
When `access` is only `FILE_GENERIC_READ` this succeeds, but when
`access` is `FILE_GENERIC_WRITE` this returns an error:
```
0x00000057, ERROR_INVALID_PARAMETER, The parameter is incorrect.
```
The reason is that `FILE_GENERIC_WRITE` includes `FILE_APPEND_DATA`,
but `FILE_APPEND_DATA` and `FILE_FLAG_NO_BUFFERING` are mutually
exclusive:
```
FILE_GENERIC_WRITE = STANDARD_RIGHTS_WRITE |
FILE_WRITE_DATA |
FILE_WRITE_ATTRIBUTES |
FILE_WRITE_EA |
FILE_APPEND_DATA |
SYNCHRONIZE
```
This incompatibility between access and attribute flags does not appear
to be documented by Microsoft for `FILE_FLAG_NO_BUFFERING` but it is
indirectly documented under [NtCreateFile](https://bit.ly/2rm5wRT):
```
FILE_NO_INTERMEDIATE_BUFFERING
The file cannot be cached or buffered in a driver's internal buffers.
This flag is incompatible with the DesiredAccess FILE_APPEND_DATA flag.
```
The solution is to remove `FILE_APPEND_DATA` from the access flags when
`FILE_FLAG_NO_BUFFERING` is set. Note that this does not prevent
appends, since `FILE_GENERIC_WRITE` also includes `FILE_WRITE_DATA`,
which in turn allows appends.

Fixes uv_fs_stat and uv_fs_lstat returning EINVAL when invoked on a
non-symlink reparse point.
1. Only tries to read symlinks when invoked via lstat (do_lstat == 1).
Rationale is that only lstat can set S_IFLNK because when a file is
tested by stat, symlinks are resolved by the OS and the returned file
must be real. Note that broken symlinks fail at CreateFile.
FILE_ATTRIBUTE_REPARSE_POINT is used by filesystem drivers for purposes
besides symlinks, and uv_fs_stat fails when invoked on these files
because fs__readlink_handle returns ERROR_SYMLINK_NOT_SUPPORTED. By
ignoring the attribute in uv_fs_stat, these files are now handled
correctly.
2. Modifies the logic added to fs__stat_handle to fix#995 as follows:
A failed fs__readlink_handle on a file with a reparse point indicates
that the file is not a symlink. The fix for #995 added code to fall
through and behave as with a normal file in this case. However, this is
not correct because lstat had opened the file with
FILE_FLAG_OPEN_REPARSE_POINT, preventing the filesystem from acting
based on the reparse point contents.
The fix makes fs__stat_handle fail back to the higher level
fs__stat_impl, which sets do_lstat to 0 and re-opens the file without
FILE_FLAG_OPEN_REPARSE_POINT, allowing normal filesystem processing to
take place.
This is also a slightly cleaner solution as symlink fallback is only
handled in one place (fs__stat_impl) instead of two (fs__stat_impl and
fs__stat_handle).
Note that the error tested in the fix for #995,
ERROR_NOT_A_REPARSE_POINT, is not actually returned by Windows in the
case of a non-symlink reparse point. I attempted to reproduce the error
by repeating the test steps in the issue but failed. However, the the
fix logic is preserved out of caution.
3. Adds tests to fs-test.c for the above two changes.
Thorough testing requires some non-trivial setup - like an OSX computer
on the LAN or a custom filesystem driver - so these tests are left
commented out for manual invocation.
